In a PID controller, what does the integral term do?
Step 1: Understand that a PID controller is used to control a system by adjusting its output based on the error between the desired setpoint and the actual output.
Step 2: Recognize that the error is the difference between the setpoint and the actual output.
Step 3: Learn that the integral term in the PID controller adds up all the past errors over time.
Step 4: Realize that by accumulating these errors, the integral term helps to address any persistent error that remains even after the proportional and derivative actions have been applied.
Step 5: Conclude that the integral term helps to eliminate steady-state error, which is the error that remains when the system has settled.
